FlowTech Purple Hornies Mufflers Reviews


Horniest turndown

Reviewed By Drake S (PRAIRIE DU CHIEN, WI) Reviewed for a 1974 Plymouth Roadrunner —9/5/2017 11:29 AM

Arrived quickly and in good order. Mounted easy on my flowtech ceramics. Have them on a mild 360 and they sound really nice not excessively loud, but they get some good attention.

Flowmaster Super 44 Series Mufflers Reviews


2010 Dodge Charger SXT 3.5L Dual Exhaust Super 44

Reviewed By Josh A (COLORADO SPRINGS, CO) Reviewed for a 2010 Dodge Charger —1/12/2018 8:08 PM

Super 44 installed in about 15 minutes. Looks great, Sounds outstanding. Brings out the lows sound, nice rumble at idle, and makes a V6 sound l8ke a V8. Also, noticeable improvement in wheel torque, smoothed out the peaks in the power band, with a net result of faster acceleration.
